12 Audio
You can use not only video images on the XO device, but also audio – both in and out.
12.1 Audio IN
Audio input is available from the IP cameras. The iFT Series does not support analogue audio in.
For cameras with an audio input, you can choose to record audio, and listen to audio in the live view. For an
overview of IP cameras that support audio in, see the
Supported IP Camera List (26742).
Note
l
If the connection bandwidth is low, it is recommended to disable live audio streaming.
l
Audio IN is unbalanced audio.
l
Changing the audio settings requires a system restart.
In the XO client, you have to enable the audio inputs for recording and listening in the live view. For more
information, see the
XO Client Software User Manual (21796).
12.2 Audio OUT (Talkback)
12.2.1 Options
Talkback to the site works via the Live Video window in the XO client software. You select a camera, and then
use the microphone (typically connected to the client PC) to talk to the site via the speaker that is associated with
that camera.
If you need only one speaker on your site, you have the following options:
l
Connect an amplified loudspeaker to the audio out plug of the motherboard (= green 3.5 mm jack).
l
Connect an amplified loudspeaker to the audio output on the MIO card (with built-in MIO card only, not
available on an external XO I/O Interface USB module).
In this case, all cameras are automatically associated with that one speaker.
If you need more than one speaker (audio zoning) on your site, you have the following options:
l
Use VM22A audio units (with built-in MIO card only) to connect up to 20 loudspeakers. Install one or two
VM22A units connected in cascade:
o
Unit 0 is controlled by the MIO card, and drives loudspeakers 1 to 10.
o
Unit 1 connects to unit 0 via the loop connector on the VM22A, and drives loudspeakers 11 to 20.
